When I make a shrimp bisque and I'd like to extract those wonderful juices from the shrimp heads and shells, my tool of choice is a potato ricer.
Of course the potato ricer's primary function is for making potato gnocchi. And it's the best tool to use to mash potatoes and avoid overworking the potatoes. With a mixer you end up with a starchy, gluey mess.
Start thinking about it for other small kitchen jobs too because it's a wonderful tool. Use it to purée other cooked vegetables, to juice lemons, to remove excess liquid from spinach and the list goes on!
